The introduction of technology to make decisions in cricket will ultimately change the nature of the game.
The introduction of replays for runouts and stumpings has been the thin end of the wedge and means that performances of players are no longer comparable to those of the pre-techno days.
For example would Bradman have had such an extraordinary average ?
The referral system is past being the thin end of the wedge, as now the technology is involved in making more decisions, people are are refusing to accept the umpires decision unless it can be "proven" with technology. despite the acknowledged "interpretation" used to generate the Snicko and the Hawkeye methods
The introduction of the referral system has several disadvantages. It continues the undermining of the umpires authority over the game, only a limited number of decisions can be referred, the possibilty of no balls are checked on referral but not at any other time and it has introduced yet another delay into the game.
The umpires authority has been continually undermined and never seriously been addressed, the unfairness of only 2 referrrals perinnings is obvious, the issue of over-rate to provide spectators some value for money has simply been ignored and in light of the new system, less overs will be bowled.
The introduction of the delay is an example of TV's control over the game. In the Melbourne Age a couple of weeks ago there was an article stating that the tension generated by the referral system made watching the game more interesting, therefore the longer the delay in the decision making is drawn out the less likely a viewer will be to change the channel.
Over rates ? The channel will show six and half hours of cricket regardless of how many overs as long as it keep the viewers.
So the good part ?
The reduction in agressive appeals and increased likelihood of batsmen walking, due to the limited number of referrals available.You wouldn't want to be the bloke who wasted a referral when you knew you were out .
And if a bowler appeals ? "If you are fair dinkum, refer it mate" !
